The cryptocurrency sector suffered heavy losses in August 2025, as 16 major security breaches wiped out more than $163 million, according to blockchain security reports. The figure marks a 15% rise from July’s $142 million, underscoring the growing scale and sophistication of attacks.
The biggest case involved an individual Bitcoin holder who lost $91.4 million in a social engineering scam. Turkey’s BtcTurk exchange followed, with attackers draining between $48 million and $54 million from its hot wallets. Other notable incidents included losses at ODIN•FUN ($7 million), BetterBank.io ($5 million), and CrediXFinance ($4.5 million). The diversity of victims highlights the range of vulnerabilities in the ecosystem, from weak private key management to exchange security lapses and smart contract flaws.
Hacking Groups Linked to North Korea
A significant share of global crypto theft continues to be linked to North Korean hacking groups. Reports estimate that they stole $1.6 billion during the first half of 2025, representing around 70% of total global losses. These operations combine advanced on-chain exploitation with social engineering, including fake job applications that allow hackers to gain insider access to companies’ systems.
Beyond exchanges and individual users, Real-World Asset (RWA) tokenization platforms are increasingly targeted. A report by Certik found that around $14.6 million was lost in attacks on RWA projects in the first half of 2025. Since these platforms connect blockchain infrastructure with traditional assets, they present multiple weak points for attackers.

The rise in August attacks shows that crypto crime is moving beyond isolated hacks toward more systematic and long-term strategies. The use of both technical exploits and human infiltration points to an evolving threat landscape that continues to test the resilience of blockchain security.
